Garry Kasparov – X3D Fritz
X3D Man-Machine World Championship. Game 1
New York, 11.11.2003
1.Nf3 Kasparov almost always opens with 1.e4 these days, at least against humans. But over the course of his 25 year professional career he has played just about everything.
1...d5 2.c4 c6 3.d4 Nf6 4.Nc3 e6 (D1) Logical and normal development into what is called the Slav Defense. This is a well-known system that is particularly well-known to... Garry Kasparov! The X3D Fritz team shows no fear and heads right into Kasparov's strength.
They wanted to show they didn't fear his preparation. This choice is also relevant because in Kasparov's last computer match, against Deep Junior in January '03, he crushed the machine in this exact opening in the first game!
5.e3 Nbd7 6.Qc2 Bd6 [6...b6 7.cxd5 exd5 8.Bd3 Be7 9.Bd2 0-0 10.g4 Nxg4 11.Rg1 Ndf6 0-1 Kasparov,G-DEEP JUNIOR/New York USA 2003/(36)]
7.g4 A very aggressive move that offers a pawn in exchange for attacking chances. If Black captures the pawn with ..Nxg5 White gets a lot of pressure on the open g-file. Kasparov has played this position three times, twice with white and once with black! He won all three games, including one against the computer program Deep Junior earlier this year.
7...Bb4 A normal move still in the "book" of both players. X3D Fritz has almost three million positions in its library of opening moves and sequences. Kasparov is legendary for his opening preparation and knowledge. He is a walking encyclopedia of opening theory and his opponents have a healthy fear of his surprises in the openings.
This move also takes the game away from the game Kasparov won against Deep Junior in this line. That's a sort of psychological advantage, being the first to spring something unexpected. Between two humans it could also be sort of like a game of chicken, with the first player to turn off from the previous game being the chicken. No matter how well it plays chess, this aspect is lost on X3D Fritz. It is not, however, lost on its creators and operators!
